I' new to this. I have iPhone 6. When I go to the interval screen to set the interval, it won't return to home screen to let me start the time lapse sequence. It's the same with the other settings. Any suggestions?

Thanks. I will try to do that in the next dayOr two. We're on the road at the moment. When I went into frames per second just now, I was not able to get out of that one, either. The problem seemed the same with all the settings screens. It's an iPhone 6+ with latest OS. I couldn't seem to get a screen shot but will try again.
